= Rank of the elliptic curve over the rational numbers
{synonym}

<Mordell's theorem> guarantees that <rank of a group>[the rank] (number of elements in the <generating set of the group>) is always well defined for an <elliptic curve over the rational numbers>. But as of 2023 there is no known algorithm which calculates the rank of any curve!

TODO list of known values and algorithms? The <Birch and Swinnerton-Dyer conjecture> would immediately provide a stupid algorithm for it.
